Evanston Chrysler Sunbeam 1942 Production .45 ACP
20/03/13 12:02 AM

Testing some loads the other day. Old WW2 production steel-cased/steel-jacketed .45 ACP. I was impressed the Extreme Spread was only 25 fps on 70 year old ammo. Admittedly only for three shots chronographed, but still...

But at 759 fps this is quite under spec for military ammo of the day. Due to the ES, I do not think the ammo has degraded.

Anyway, I was testing the steel-jacketed bullets on my pistol plate. Technical material from US Army Ordnance addresses the superior penetrative performance of steel-jacketed .45 bullets over the regular gilding metal clad jobs. My test indicated a little better performance than standard fare. With bullets running 100 fps faster {milspec} I'd expect full penetration thru the plate. The plate is .081 thick of unknown metallurgy. Probably mild steel.

.45 ammo always appears anemic in steel plate tests and Uncle was always interested in bettering the performance. A steel-core, steel jacketed 200 grain bullet running 1000 fps or a little better would have sealed the deal. But it never got to see the light of day, and I've never seen where they ever tried such a thing.

Anyway...

ECS 42 on the left. The other stuff is WW1 production cupronickel, etc.

Hanging on the cow magnet. The stuff;
